TRS3122E: About estimation of power consumption

Part Number: TRS3122E



Regarding to estimation of power consumption at 32Kbps on TRS3122E, my customer is asking some question.

They are referring below characteristic(datasheet page6,Figure 1) for power consumption.


(1)About supply current (Y-axis) in Figure 1.

Does it mean current on VL(Logic-level supply) or Vcc(supply voltage)?

(2) They understand as following about Figure 1.

Driver2 is on 32Kbps and it means the supply current of Driver1 each 250/500/1000kbps.

If so, how does the receiver power consumption estimate?

Can the drive current of receiver estimate as power consumption ?

(3) Do you have the supply current data at 32kbps on Figure 1?
